What this skill does
Verification Loop Skill A comprehensive verification system for Claude Code sessions. When to Use Invoke this skill: After completing a feature or significant code change Before creating a PR When you want to ensure quality gates pass After refactoring Verification Phases Phase 1: Build Verification If build fails, STOP and fix before continuing. Phase 2: Type Check Report all type errors. Fix critical ones before continuing. Phase 3: Lint Check Phase 4: Test Suite Report: Total tests: X Passed: X Failed: X Coverage: X% Phase 5: Security Scan Phase 6: Diff Review Review each changed file for: Unintended changes Missing error handling Potential edge cases Target Acceptance When the requested outcome requires deployment or target-environment verification, report target acceptance separately from local checks. Record the environment and installed version when known, the evidence, and the next permitted check or precise access dependency. Passing local checks, review, merge, or release does not establish target acceptance. Report VERIFIED or FAILED for an executed target check, with its evidence. Do not access production or make external changes without authorization. For local-only tasks, mark target acceptance as not applicable. For example: local checks PASS; staging verification NOT PERFORMED (no access); next step: an authorized maintainer runs the staging smoke test. Output Format After running all phases, produce a verification report: Continuous Mode For long sessions, run verification every 15 minutes or after major changes: Integration with Hooks This skill complements PostToolUse hooks but provides deeper verification. Hooks catch issues immediately; this skill provides comprehensive review.
